Mahle Rings Perf Gas Nitride Steel 4.160in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

This is a bulk pack of 48 Mahle OE Performance Gas Nitride Steel Piston Rings, designed for a 4.160-inch bore. These rings feature a .043-inch thickness and a nitride coating, which is a durable surface treatment that helps reduce friction and wear. This specific set is intended for performance gasoline engine applications where reliability and consistent sealing are crucial.

Mahle is a well-known name in engine components, and these rings are built to meet the demands of performance builds. The nitride treatment on the steel rings provides a hard, wear-resistant surface that can withstand the higher temperatures and pressures often found in performance engines. This helps ensure a good seal between the piston and cylinder wall, which is essential for maintaining compression and preventing blow-by. The .157-inch ring width is a common specification for many performance applications, ensuring compatibility with a wide range of pistons.

This bulk pack is ideal for engine builders or shops that frequently work on performance gasoline engines and require a quantity of these specific rings. While these rings are designed for performance, it's important to note they are not CARB approved and cannot be shipped to California. Always refer to your engine's specific build requirements and manufacturer's recommendations to ensure proper fitment and performance.
